Export: PDF/DOCX-Dateimetadaten (Title, Author, Subject, Keywords, Category, Comments)

- Neue Helper-Funktion _build_export_metadata baut einheitliches Metadaten-Dict
- PDF via HTML-Meta-Tags (title, author, description, keywords, generator, lang)
- DOCX via doc.core_properties (title, author, subject, keywords, comments,
  category, last_modified_by, language, content_status, created, modified)
- Keywords aus OSINT + Typ + Organisation + category_labels + Top-5-Orten
- Comments-Feld mit strukturiertem Block (Incident-ID, Typ, Scope, Umfang, Orte)
- Router laedt Organisation + Top-Orte aus article_locations und reicht sie durch
